BATTERY-CONNECTOR,

arw- Application filed January 9, 1914, Serial No. 811,151. Renewed February 4, 1916.

To all ii mm it may concern:

lie it known that I, Fnnmnnon VVRIGI-rr, a citizen of the United States, residing at Piiughlecpsie, Dutchc New York, have invented certain new and useful improvements in lMttcry-Connectors; and I do hereby declare the following to be a full, clear, and exact descrhption of the invention, such as will enable others skilled in the art to which it lLPPOIiZfllIIS to make and use the same.

It is the object of the present invention to storage battery cells may be electrically conncctcd together.

in storage battery work it is not ordinarily feasible to use exposed conductors of copper 'or brass near the batteries then1- :tcivos. bceiu-isc of the corroding action of the sulfuric acid used iii the batteries and of the vapors given oil by the batteries duringz; charging. It is desirable that all connoetingr; parts be of lead or lead covered.

The connector of the presentfinvention salislics the above requirements and has the further advantage oi high conductivity, and is particularly well suited for use on a factory scale, for it is in many respects fool proof and reliable even under factory conditions.

The details of the invention and other ailvantagcs and characteristic features will be made clear by the following detailed desrription. which is to be taken in conjunction with the accompanying drawings, wherein Figure 1 is a diagram showing the top oi. a storage battery comprising three cells connected in series; Fig. 2 is a. plan view of a connector constructed in accordance with the present invention; Fig. 3 is an assembly showing the studs of two adjacent sets of battery plates and the connector in position for union with those studs by burning, and F l is a cross-sectional elevation of the completed connection between the two sets of plates.

The battcry of Fig. 1 comprises three cells, 1, 2 and 3, and is of a type well suited for use on automobiles as a part of the electrical starting systcn'i or of the ignition sysconnty, State of Patented Sept. 5, i916.

farther wall of each of the rings 8 and 9.

Flg. 3 shows iragn'ients of a group oi battery plates 12 welded to a head 13 from which .IJSQS a stud 1-1, and a similar set of plates in an adjacent cell is provided with "a stud 15, and it is the function of the cross,

connection to establish a permanent electrical path of good conductivity between these two studs. This result is attained by dropping the. cross-connection down at the top of studs 14 and 15 until the copper rod 11 strikes against those tops. Then torches are applied through the op'eningsin rings 8 and 9, and the tops of studs 14: and

15 are limited or softcned,.and tin? rod 11 sinksadownthrough them until th entire openings within rings 8 and 9' are filled with metal. Then the structure is allowed to cool and, if desired, may be smoothed off at the top to give a finished appearance. n

The joint as complete isqillustratcd in Fig. 4-, and it will be seen that the studs 14 and 15 have been i'ncrged by fusio into the rings 8 and 9, and the copper 11 fun nishcs a highly conductive path tor cur rent from one stud ,to the other; Vi ith this form of connectiona careless Workman cannot make an incomplete weld, because is not possible to force the cross-connection down to final position on studs Hand 15 ni'itil-their tops have been rendered suil'icicntly molten to open and receive the rod 11, and when they have been heated suilicientlyt for this purpose, a good union with the lead and copper'oit the connection is insured.

lVhcn the joint is complete, the entir'e cross-section of each of the studs 14 and 15 is available for carrying current, for the rod 11 extends entirely across the top of, each stud and lies directly in the path of current flowing from one stud to the other.

in the completctl joint the copper rod is conipleteiy enveloped in lead and oroteeted from corrosion.

I claim: 1. A battery connector comprising a pair oi: lead rings connected by a lead'shunk, and

metal bar of good conductivity passing through said shank and across the openings in said rings.

2. A battery connector comprising a panof lead rings connected by a lead shank, and a copper rod passing through said. shank md into the ODPJU'HQS of said r: n gs.
